 Abstract
A flexible and accurate unstructured finite volume method is presented for two dimensions incompressible flows. It allows a mesh of arbitrary polygons, and a higher order upwind scheme, a modified QUICK, is used to discritize the convective terms in the momentum equations. All dependent variables, velocity components and pressure, are stored at the same grid point. A pressure equation is derived from the continuity equation. Present method is validated through calculation of several laminar and turbulent flows. All turbulent flows arc calculated with Baldwin-Lomax model. All numerical solutions show good agreement with previous experiment and/or numerical solutions. Triangular mesh shows better prediction, in terms of accuracy and convergence speed, over quadrilateral mesh in general, and this improvement is believed to come from accurate calculation of flux crossing the control volume
